Estimation of Geodynamic Activity and Its Effect on Mining-Geological Conditions And Flooding of Potassium Mines

摘要

The problem of forecasting of geodynamic dangerous zones at early stage of potash deposits development is very important for providing safe mining operation. In result of insufficient geological studies and /or improper mine planning more than 80 potash mines have been flooded over the past 150 years in the world. The author and others have developed special techniques for assessing geodynamic (neotectonic) activity of territories - morphoneotectonic, lineament-geodynamic and landscape-geodynamic analyzes based on remote sensing, which allow to reliably establish geoactive zones of various levels - from regional (with areas of hundreds and thousands km2) to local (with areas less than 1 km2). The used methodology includes analysis of the remote sensing data at different scale and defining the spatial distribution of the neotectonic indicators, the most important of which is a density of lineaments. The results of the analysis of modern tectonics and geodynamics in the area of the Verkhnekamskoye potassium salt deposit (Russia, Perm Territory) - the largest in the world and best studied by various geological and geophysical methods, as well as Zhilyanskoe (Kazakhstan) and Tyubegatanskoye (Uzbekistan, Turkmenistan) potassium salt deposits.
